Hi Guys,

Below is a message I posted on the metalworking newsgroup. I am hoping the
soemone can help me with the wiring to the motor, magnetic starter and
pressure switch.

My sincerest thanks for the help.

Joe...

I got my hands on a 1972 80 gallon 2 stage compressor. The pump is a Quincy
model 325 13. I understand that this is the compressor on their QR series
machines. It is in great shape, has a 5 HP Single Phase Motor and a
magnetic starter. All the wiring has been removed.

Here are some questions I hope you can help me with:

What order does the unit get wired in? Is it line voltage to - pressure
switch to magnetic starter to motor?

What kind of oil should I use?

It is missing the air filter assembly, where can I purchase a new one?

Where would I get repacement drive belts?

My sincerest thanks.

Joe...

I have no clue to you exact unit. Typically Line 1 will land at the top of
the starter and splice off to the pressure switch. From the pressure switch
it comes back to the 120 volt coil,,,, I AM guessing. Coil could be 220
volt. Line 2 would also land on the top of the starter. Be sure to ground
all metal surfaces. Some where near the unit there should be a safety
disconnect switch, in series where may be an on-off switch.

Oil type should be stated on the unit.

Belts are easy, measure the width, depth, and length and go to a real parts
house. IF there are several belts make sure that your buying matched belts
if your planning on having this running for long periods of time.

Phil,

My sincerest thanks for your help. Are there any disadvantages to wiring
the compressor without a magnetic starter?

Thanks again.

Joe..
